What is Corporation Tax?
UK corporation tax is a tax paid by UK limited companies on their annual profits. Profit is calculated as your total revenue minus any allowable business expenses. It is administered by His Majesty's Revenue and Customs (HMRC).
Every UK limited company must file a Company Tax Return (Form CT600), regardless of whether it made a profit or a loss. Understanding UK Corporation Tax requirements is essential for businesses to maintain proper UK tax compliance and meet their reporting obligations.
Corporation Tax Rates
As of April 2023, the UK Corporation Tax rates are as follows:
- The main rate of Corporation Tax is 25% for companies with profits over £250,000.
- The small profits rate is 19% for companies with profits of £50,000 or less.
- Companies with profits between £50,000 and £250,000 pay tax at the main rate but can claim Marginal Relief, which provides a gradual increase in the effective tax rate.
For most startups in their early years, the 19% rate will likely apply. Businesses should understand the applicable corporation tax rates to accurately estimate their tax liabilities and manage their finances.
Filing Deadlines
UK Corporation Tax involves two key deadlines, and they are different.
- Deadline to Pay: Your Corporation Tax bill must be paid 9 months and 1 day after the end of your company's accounting period.
- Deadline to File: Your Company Tax Return (CT600) must be filed 12 months after the end of your accounting period.
It's crucial to note that you must pay your tax before you file your return. Late payment incurs interest, and late filing incurs penalties. Understanding corporation tax filing deadlines helps businesses maintain accurate and timelyUK tax compliance.
